Dishonored is $10 again so I picked that up along with Hitman Absolution for about $7.
The prices don't match between UK Steam and US.
Dishonored and Absolution are both Ł4.99 UK side, which is like $7.68.
I wonder if you could use VPN to shop around for the best prices? I heard the games are really cheap if you're buying from an Indian IP address.
